Formula

Core Formula

\text{Rate (mL/hr)} = \frac{\text{Total Volume (mL)}}{\text{Time (Hours)}}

How it works: Determines the setting for an IV infusion pump based on total volume and desired duration.

Worked Example

1000 mL over 8 hours -> 1000 / 8 = 125 mL/hr.

Frequently Asked Questions

Why use mL per hour?

Most electronic infusion pumps are programmed in mL per hour to ensure consistent and precise fluid delivery over a long duration.

How is this different from drip rate?

Infusion rate (mL/hr) is for pumps, while drip rate (gtt/min) is for manual IV gravity sets where you count the drops.

What if the time is in minutes?

Divide the minutes by 60 to get hours. For example, 30 minutes is 0.5 hours.
